Subject: Creating directory and its files

Hi there:
I want to create a directory and create files under it.
I can use

FileUtils.mkdir_p ARGV[0]

to create a directory, however if the directory already exist, program
will
generate error messages:

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:243:in
`mkdir': File exists - ETFlist (Errno::EEXIST)
        from
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:243:in
`fu_mkdir'
        from
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:217:in
`mkdir_p'
        from
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:215:in
`reverse_each'
        from
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:215:in
`mkdir_p'
        from
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:201:in
`each'
        from
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:201:in
`mkdir_p'


Please tell me how to solve this problem.

Thank you so much.
